Application filed July 291914.

in it lgimun that l, (inns); G. (harness, a citizen of the l lilii lil Slates, residing 21tli'urrvu. iii the (county of \Vurron and. State of Pennsylvania. have inwiilcil certain new and llSli lll lniprm'vnieiiis in fosters, of which the following 2: specification. reference being hzul lherein to the accompanying drawing.

This inveniion relulos to cor'min new and useful improvements in masters and more particularly to conteriiig in ii retaining means flu holding sl'e caster in its proper position u'ilhin a luhulur leg; the ohjecl: boing to provide :1 cunt-wing and retaining device which is i eeiilingljv simple and cheap in construction and m in which the easier pintl iim'n'uineutly stoned.

Anoihsr ohioot of the invention is in pro ride :1 (flib'iifl' in which the centering retaining uwmher ii woof. is formed of substantially inverted L -shaped nrnisprefer- :ihly loriuoil of spring wirss mounti ul wr'h in a lmsc- 22ml. connsoaw" to :1 cap which rosis upon he to}; of ihe pintle in order to allow the pintle in rotate if "only: said spring arms hearing against tho inner face of the tubular leg in order to holil the cnsterin its proper posiiimi h friniinnul contact.

Another object of the im 1- ion is to provide novel moans for securing the inverted U-shnpecl arms in position upon the cap, whereby the centering and retaining; 1118111 her can iii; -inui'acturerl cheaply and applied to 21 z? i, or.

In orclor to cu fasten the pintiou'i in the centering and retaining niomhvr. same 15 upset to iorm upon the pintlesnd it will he no these lugs are slightly spaced from the supporting base 5 in order to allow a slight vertical IHUYQIl'lQllt of the same upon the pintlo.

In this mnniuiiglhecentering and retaining 165 member IS locked in position upon the pintls of the caster in such a. manner that the same is allowed to roluiiv freely but is pre ented from lining .lllOv'Bt'l \(fi'tlfiilllf/ from oil of *he pint-ls. 11a

in the nimlilimilious shown in i the ouster frame 1 is constructed 1 with that'shown in the preferred form and a centering and retaining member 13 is substantially the same 2with the exception that one pair of the spring-arms 14 thereof extend through openings} 15' of the base 16;

cannot be removed, whereby all danger-of the caster. being accidentally withdrawn from the centering and retaining member is prevented and an exceed1ngly simple and cheap qinstruction of centering and retain ring member-1s formedwhich when in posi-' tion Within a, tnbular leg, will securely hold andcenter. the caster therein. This con-- struction of centering and retaining memher is especially adapted to be used in connection with tubular legs of small diameters and upon a cheap class-of furniture.

I claim:

The combination with'a caster, having a i I pintle provided with a rounded upper end,

of a tubular-shaped cap having a socket corresponding in shape to the upper end of said pintle mounted thereon, cross arms pro vided with reduced portions interlocked together and secured upon the top of said cap,

and a base surrounding" said pintle carried of said arms, said zpintle having by the ends projections for limiting the upward move ment of said base upon said piri'tle. i

In testimony whereof I aflix my signature in presence of twowitnesses.
